904 | | |
905 | | We need to be careful in how we match section names because of the support |
906 | | for wildcard characters. For example suppose that the user has invoked |
907 | | objcopy like this: |
908 | | |
909 | | --set-section-flags .debug_*=debug |
910 | | --set-section-flags .debug_str=readonly,debug |
911 | | --change-section-address .debug_*ranges=0x1000 |
912 | | |
913 | | With the idea that all debug sections will receive the DEBUG flag, the |
914 | | .debug_str section will also receive the READONLY flag and the |
915 | | .debug_ranges and .debug_aranges sections will have their address set to |
916 | | 0x1000. (This may not make much sense, but it is just an example). |
917 | | |
918 | | When adding the section name patterns to the section list we need to make |
919 | | sure that previous entries do not match with the new entry, unless the |
920 | | match is exact. (In which case we assume that the user is overriding |
921 | | the previous entry with the new context). |
922 | | |
923 | | When matching real section names to the section list we make use of the |
924 | | wildcard characters, but we must do so in context. Eg if we are setting |
925 | | section addresses then we match for .debug_ranges but not for .debug_info. |
926 | | |
927 | | Finally, if ADD is false and we do find a match, we mark the section list |
928 | | entry as used. */ |
